need help with command line (convert multiple files, DTS-HD MA to FLAC)

[Lucario]

Hey, I'm used to using software with command lines, like with ffmpeg, yt-dlp, mkvmerge or waifu2x. So I'm not new to that. Sadly, I was unable to find clear instructions on how a full command for makemkvcon64 should look like. There seems to be no help command. The usage.txt looks unclear/incomplete to me. A quick search via Google or in this forum showed no helpful results.

I want to input an MKV-file with two DTS-HD MA audio tracks in it, to convert these into FLAC into a different folder. I want to do that with multiple files, so if that's possible with multiple files at once, that would be a nice extra. Also a nice extra would be if it's possible to not copy the DTS-cores as separate audio tracts into the new file, as it's sadly default to do that in the GUI.

Doing that with the GUI with hundreds of files would be way to tedious. Thanks.

You sound like an idiot.

Anyways, an AI in fact helped me with my problem. This .bat-file (run within a command line) does what I want:

Code: Select all

@echo off
set MAKEMKV_PATH="[path]\makemkvcon64.exe"
set PROFILE_PATH="[path]\FLAC-best.mmcp.xml"
set INPUT_DIR="[input-folder]"
set OUTPUT_DIR="[output-folder]"

for %%f in ("%INPUT_DIR%\*.mkv") do (
    set FILENAME=%%~nf
    echo Processing %%f...
    %MAKEMKV_PATH% mkv --profile=%PROFILE_PATH% file:"%%f" all "%OUTPUT_DIR%"
)

Of course [path], [input folder], and [output folder] need to be replaced accordingly.

This is the custom FLAC-best.mmcp.xml I use:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<profile>
    <!-- profile name (will appear in GUI if you open it, but not needed for command line) -->
    <name lang="eng">FLAC-best</name>

                defaultSelection="$app_DefaultSelectionString">
        </output>
    </trackSettings>

    <!-- copies standalone multi-channel DTS tracks -->
    <trackSettings input="DTS-multi">
        <output outputSettingsName="copy"
                defaultSelection="$app_DefaultSelectionString">
        </output>
    </trackSettings>

    <!-- copies stereo DTS-HD LBR tracks -->
    <trackSettings input="DTSHDLBR-stereo">
        <output outputSettingsName="copy"
                defaultSelection="$app_DefaultSelectionString">
        </output>
    </trackSettings>

    <!-- copies multi-channel DTS-HD LBR tracks -->
    <trackSettings input="DTSHDLBR-multi">
        <output outputSettingsName="copy"
                defaultSelection="$app_DefaultSelectionString">
        </output>
    </trackSettings>
</profile>

With this, I can automatically take all MKV-files from the input-folder to the output-folder, converting any lossless audio-track into FLAC with best compression and leaving out the DTS-core-tracks, which MakeMKV otherwise by default would copy into the new files as separate audio-tracks.
